When does The Hoober-Bloob Highway return?

The Hoober-Bloob Highway is an animated musical special written by Theodor Geisel (the real name of Dr. Seuss) and produced by DePatie–Freleng Enterprises. The special first aired February 19, 1975 on CBS, and was the last Dr.Seuss special produced for that network. The story suggests that while things may be pretty bad, there is always something to be thankful for.
